Pool Maintenance Checklist (Printable)
We built this checklist as a week-to-week and season-to-season reference. Chemistry targets are embedded directly in each checklist item so you don’t need a separate reference. For the reasoning behind each task and frequency, see the detailed pool maintenance schedule. For new owners needing the full context behind these tasks, see our pool maintenance guide for beginners.
We recommend testing according to CDC pool water disinfection guidelines{:target=“_blank”}, free chlorine and pH should be tested at least twice per week for residential pools during the swim season.
A weekly pool maintenance checklist includes: free chlorine test (target 1-3 ppm), pH test (target 7.4-7.6), skimming, brushing, vacuuming, and filter pressure check. These tasks catch problems before they become expensive.
Weekly pool maintenance checklist
Chemistry tests (minimum 2x per week)
- Free Chlorine (FC): target 1-3 ppm (SWG pools: maintain per CYA level)
- pH: target 7.4-7.6 (acceptable: 7.2-7.8)
- Combined Chlorine (CC): should read 0; above 0.5 ppm = shock needed
- CYA (Cyanuric Acid): test monthly; target 30-50 ppm chlorine pools / 60-90 ppm SWG
For pool water chemistry targets and adjustment guides when any reading is off, see the chemistry hub.
Physical maintenance (weekly)
- Skim pool surface (daily or every 2 days is better; weekly minimum)
- Brush walls, floor, steps, and ladder rails, all surfaces, not just the obvious ones
- Vacuum pool floor (to filter for debris; to waste mode for algae)
- Empty skimmer basket(s)
- Check and empty pump strainer basket
- Verify pump is running and check for visible leaks at fittings
Filter check (weekly)
- Read pressure gauge
- If pressure is 8-10 PSI above baseline: clean or backwash filter now
- Record baseline after each cleaning (stick a label to the equipment pad)
For the full guide on filter pressure diagnosis, see pool filter cleaning guide.
Run time (weekly verify)
- Pump run time: 8-12 hours/day in summer
- Pump run time: 6-8 hours in shoulder seasons (spring/fall)
- Variable speed pump: verify flow rate schedule is set correctly
Monthly pool maintenance checklist
Chemistry (full panel, once per month)
- Free Chlorine (FC): target 1-3 ppm
- pH: target 7.4-7.6
- Total Alkalinity (TA): target 80-120 ppm; adjust if outside range
- Calcium Hardness (CH): 175-275 ppm (plaster: 200-275; vinyl/fiberglass: 175-225)
- CYA (Cyanuric Acid): target 30-50 ppm; drain to lower if above 80 ppm
- Adjust any parameter out of range; use correct addition order (TA first, pH second, chlorine third)
Per EPA pool water efficiency guidance{:target=“_blank”}, proper chemical balance reduces the need for water replacement and chemical overcorrections.
Equipment (monthly)
- Deep-clean filter cartridge: soak overnight in filter cleaner solution; rinse thoroughly before reinstalling
- Sand/DE filter: thorough backwash; add fresh DE (DE filters only) after backwash
- Inspect O-rings and gaskets at pump lid, filter housing, multiport valve, replace any that are cracked or dry
- Clean pool tile and waterline: remove calcium scaling and body oil film with tile cleaner
- Inspect ladders, handrails, and steps: check for rust, wobble, or instability
- Verify automatic chlorinator or chemical feeder is loading and dispensing correctly (if equipped)
- Check pool light covers for moisture infiltration (if equipped)
Optional preventive (monthly)
- Preventive algaecide dose (polyquat 60 only): add at label dose rate; only below 5 ppm FC; skip if using TFP method
- Test for metals/phosphates if water clarity has been persistently poor despite correct chemistry
Pool opening checklist (spring)
When to open: When water temperature consistently stays above 65°F. Opening earlier means algae risk is low, but it is unnecessary heating cost if the pool is not in use.
Estimated chemical cost: $85-$140 for a typical seasonal opening with standard chemistry adjustment needs.
Day 1: equipment setup
- Remove and store winter cover (clean and dry before folding for storage)
- Remove all winterizing plugs from return jets, skimmer, and main drain
- Reinstall drain plugs, filter pressure gauge, and pump basket lid
- Reconnect pump; fill pump basket with water before starting
- Start pump; check for leaks at all fittings; verify flow from all returns
- Reconnect filter; backwash (sand/DE) or inspect cartridge; reinstall clean cartridge
- Inspect multiport valve position (should be on Filter)
- Check all valves; open any that were closed for winter
Day 1: initial chemistry
- Test water before adding any chemicals (often needs less adjustment than expected)
- Adjust Total Alkalinity first if outside 80-120 ppm (baking soda to raise; muriatic acid to lower)
- Adjust pH to 7.4-7.6
- Shock: 2 lbs Cal-Hypo 65% per 10,000 gallons; green pool: 3-4 lbs per 10,000 gallons
- Run pump continuously for first 24 hours
For the full opening guide, see complete pool opening guide.
Days 2-7: establish chemistry
- Test daily for first week; adjust as needed
- Add CYA if below 30 ppm (add after shock has dissipated below 5 ppm FC)
- Add algaecide (polyquat 60 only) only after FC drops below 5 ppm; skip if water was clear from opening
- Brush daily; vacuum when water begins to clear
- Clean filter when pressure rises 8-10 PSI above post-clean baseline
- Confirm all return jets are functioning; verify pump basket stays clear
Pool closing checklist (fall)
When to close: When water temperature consistently drops below 65°F. Closing too early wastes the shoulder season. Closing with water above 65°F increases algae risk over winter.
Estimated chemical cost: $50-$150 in chemicals and supplies for a standard closing.
One week before closing
- Balance all chemistry: pH 7.2-7.8, TA 80-120 ppm, CH 175-225 ppm, FC 1-3 ppm
- Balanced water going into winter prevents surface etching and scale formation over months of inactivity
Closing day: chemicals
- Shock the night before closing: raise FC to 3-5 ppm using liquid chlorine or Cal-Hypo
- Next morning: add winter algaecide (polyquat 60), only when FC is below 5 ppm; adding into high FC destroys algaecide
- Add metal sequestrant (prevents staining from metals dropping out of solution over winter)
- Add winter slow-release floater or closing kit chemicals per label instructions
Closing day: equipment (freeze climate requirements)
- Backwash and clean filter thoroughly; store cartridges dry (important: wet cartridges mold in storage)
- Lower water level 4-6 inches below the skimmer (prevents ice expansion from damaging skimmer)
- Blow out all plumbing lines with a shop vac or compressor (mandatory in freeze climates)
- Insert winterizing plugs in all skimmer throats and return jets
- Remove ladders, handrails, and dive board; store indoors or in covered storage
- Remove pump basket; bring motor indoors if freeze temps are expected (motors are damaged by hard freezes)
- Install winter cover (solid tarp, mesh safety, or solid safety cover)
Post-storm checklist
Heavy rain and storms shift chemistry and load the filter. This checklist applies after any significant weather event.
- Skim and remove all debris immediately before it sinks and decomposes
- Check and empty skimmer basket(s)
- Test FC and pH (rain dilutes chlorine, can shift pH in either direction)
- Shock if FC is below 1 ppm (heavy rain brings organic load and dilutes sanitizer)
- Run pump 24 hours continuously after a heavy storm
- Brush all surfaces; vacuum when debris settles
- Check filter pressure; clean if pressure is elevated
FAQ
How often should I do pool maintenance?
Weekly is the minimum: chemistry tests (at least twice per week), skimming, brushing, and filter pressure check. Daily skimming in high-debris seasons (near trees, high wind) prevents decomposing leaves from loading your chemistry. Monthly is for the full chemistry panel and equipment inspection. See pool maintenance cost breakdown for what this costs annually.
What’s the most important pool maintenance task?
Weekly water chemistry testing catches problems before they become expensive. A pH swing that goes undetected for two weeks can cause surface etching (plaster pools) or staining. A chlorine crash that goes undetected for days can allow algae to establish, turning a 10-minute correction into a multi-day SLAM process. Test consistently and the corrections stay small.
Can I print this checklist?
Yes. The format is designed to be print-friendly. Screenshot or bookmark this page for pool-side reference. For the complete reasoning behind each task, see the detailed pool maintenance schedule which includes the “why” behind each frequency.
What do I do if a chemistry test fails?
Check the pool chemistry hub at pool water chemistry targets for adjustment guides for each parameter. Follow the addition sequence: Total Alkalinity first, then pH, then chlorine. Test again after 4-6 hours before adding anything else. Use a liquid test kit (Taylor K-2006 or equivalent) for accurate results if strip tests are giving inconsistent readings.
